Nordtank
55 kW
 The
55 kW generation of wind turbines which were developed in 1980
- 1981 became the industrial and technological breakthrough for
modern wind turbines.
The
cost per kilowatt hour (kWh) of electricity dropped by about
50 per cent with the appearance of this generation of wind turbines.
The wind industry became much more professionalised, and the
parallel development of the European Wind Atlas Method by Risoe
National Laboratory was extremely important in lowering kWh costs.
The
picture shows a particularly imaginative way of siting these
Nordtank 55 kW
wind turbines (43K, JPEG), on a harbour pier at the town
of Ebeltoft, Denmark. Red tipped rotor blades have disappeared
completely from the market since then, after it was discovered
that birds do not fly into
the rotors anyway.

The
Great California Wind Rush
 Literally
thousands of these machines were delivered to the wind programme
in California in the early eighties. The Micon 55 kW (69K, JPEG) is one example
of such a machine, delivered to one huge park of more than 1000
machines in Palm Springs, California.
Having
started series manufacturing of wind turbines about 5 years earlier,
Danish manufacturers had much more of a track record than companies
from other countries. About half of the wind turbines placed
in California are of Danish origin.
The
market for wind energy in the United States disappeared overnight
with the disappearance of the Californian support schemes around
1985. Since then, only a tiny trickle of new installations have
been commissioned, although the market seems to have been picking
up, lately. Germany is now the world's main market, and the country
with the largest wind power installation.
